DYSL was formed in the mid 1980s as an alternative to girls playing baseball. The league accepts both genders as players but traditionally girls participate almost exclusively.

In the early 2000s DYSL became an affiliate of Babe Ruth League and operates under its regulations. We offer softball for players ranging in age from 4-16, and sometimes up to 18. Our jurisdiction includes the communities of Dover, Somersworth, Rollinsford and Berwick, ME. However, players from other communities who attend a Dover school may also play in our league.
